thanx

Eneloop completed at 1564 shoots and Imedion completed at 1660, approximately 100 shots more than Eneloop, which is pretty much expected as it is a 2100mAh vs 2000mAh, with approximately 5% extra power. For a fair comparison, the first 1500 shots are only taken into account, which is already beyond what average number of photos a person can take on a whole day event (with speedlight)

On cycle performance point of view, Eneloop out performed Imedion from 4rpm to 14rpm with an amazing everage of 6rpm on a consistant performance.

In this experiment, it is concluded that the Sanyo Eneloop is a better performer than PowerEx Imedion, at least on a speedlight point of view.

Thanks for your review of these batteries. In addition to the Servaas ‘Low Self Discharge rechargeable AA battery test results’, you might be interested in the results of a more extensive three month comparison test of AA NiMH Low Self Discharge Batteries here –

AA and AAA NiMH low self-discharge tests–Round 2

The PowerEx IMEDION AA batteries top the ratings with the highest mAh capacity and levels at three months. Kodak Pre-Charged batteries were second (and may be cheaper and easily obtained for many), with GP ReCyko in third and Duracell Precharged AA batteries in fourth. Sanyo Eneloop is in eighth place.

There is quite a bit of activity regarding ‘Low Self Discharge Batteries’ on Candlepowerforums.com, but this link shows the AA NiMH Low Self-Discharge Test graph.

I recently purchased some PowerEx IMEDIONs and Kodak Pre-Charged AA and AAA batteries due to this test.
